abstract = {Carbohydrate esterases modify polysaccharides by removing
different ester moieties thereby affecting their
physicochemical properties and their accessibility by
glycoside hydrolases. We determined the full-length
structures of two members $(Fl8CE20_II$ and $PpCE20_II)$
from the carbohydrate esterase family 20 (CE20) by X-ray
crystallography that feature an ancillary domain, inserted
into the catalytic SGNH-hydrolase domain. Detailed
structural analysis identifies a so far undescribed
catalytic triad architecture which lacks the typical
aspartate for polarization of the histidine but instead
reveals a precisely coordinated water molecule mediating
contact between the His and Asp. This coordinated water in
the Ser-His-(H2O-Asp/Asn) motif, as further confirmed by
mutational studies and by determination of kinetic
constants, is crucial for catalytic activity. We therefore
term this active site architecture a water-mediated
catalytic triad.},
